Parameters
memoryStoreID: string
memoryID: string
view?:optional ManagedAgentsMemoryView

Query parameter for view

betas?:optional list<AnthropicBeta>

Optional header to specify the beta version(s) you want to use.

workspaceID?:optional string
Returns
class ManagedAgentsMemory { $type; $id; $contentSha256; /* 7 more */ }
Type type
string id

Unique identifier for this memory (a mem_... value). Stable across renames; use this ID, not the path, to read, update, or delete the memory.

string contentSha256

Lowercase hex SHA-256 digest of the UTF-8 content bytes (64 characters). The server applies no normalization, so clients can compute the same hash locally for staleness checks and as the value for a content_sha256 precondition on update. Always populated, regardless of view.

int contentSizeBytes

Size of content in bytes (the UTF-8 plaintext length). Always populated, regardless of view.

\Datetime createdAt

A timestamp in RFC 3339 format

string memoryStoreID

ID of the memory store this memory belongs to (a memstore_... value).

string memoryVersionID

ID of the memory_version representing this memory's current content (a memver_... value). This is the authoritative head pointer; memory_version objects do not carry an is_latest flag, so compare against this field instead. Enumerate the history via List memory versions.

string path

Hierarchical path of the memory within the store, e.g. /projects/foo/notes.md. Always starts with /. Paths are case-sensitive and unique within a store. Maximum 1,024 bytes.

\Datetime updatedAt

A timestamp in RFC 3339 format

?string content

The memory's UTF-8 text content. Populated when view=full; null when view=basic. Maximum 100 kB (102,400 bytes).
